目的:初步探讨音猬因子（SHH）信号通路抑制剂NVP-LDE225与放射联用治疗黑色素瘤的潜在作用机制以及可行性。方法:通过qPCR的方法检测处理前后黑色素瘤细胞Melan-A及SK-MEL-2中Gli1的mRNA的表达量。NVP-LDE225、GDC-0449与放射联合处理24 h后，通过细胞计数法和CCK-8法检测黑色素瘤细胞Melan-A及SK-MEL-2的细胞数量与细胞活性，细胞克隆法检测Melan-A及SK-MEL-2的生存以及增殖能力，流式细胞术检测Melan-A细胞周期的变化，Western blot检测Melan-A细胞中凋亡蛋白Bax及Caspase3的表达变化。结果:单纯给予Smo抑制剂NVP-LDE225能够抑制黑色素瘤细胞中Gli1的mRNA表达，减少黑色素瘤细胞的增殖，诱导...

Objective:To explore the potential mechanism and feasibility of sonic hedgehog (SHH) signal pathway inhibitor NVP-LDE225 combined with radiotherapy in the treatment of melanoma.Methods:The Gli1 mRNA expression of the melanoma cells (Melan-A and SK-MEL-2) was detected by qPCR. After treatment with NVP-LDE225, GDC-0449 or combined with radiation for 24 hours, the number and activity of Melan-A and SK-MEL-2 were detected by cell counting and CCK-8 kit. The survival and proliferation ratio of Melan-A and SK-MEL-2 were detected by cell cloning. The changes of cell cycle of melanoma Melan-A cells we...
